Fehllage Gastrostomiekatheter

Infant who

has just undergone a gastrostomy tube replacement which was technically difficultAP image from a gastrostomy tube injection done with water soluble contrast (left) shows none of the injected contrast conforming to the lumenal contour of the stomach. AXR taken 15 minutes later (right) shows the extravasated contrast diffusing throughout the peritoneum and outlining loops of bowel and being excreted in the bladder.The diagnosis was malposition of the gastrostomy tube replacement outside of the stomach.

Infant with

vomiting after gastrostomy tube placement a week agoAP image during an enema shows a fixed lumenal caliber change or filling defect caused by the gastrostomy tube balloon in the mid transverse colon. Early lateral image during gastrostomy tube injection with water soluble contrast (above right) shows the gastrostomy balloon and tip within the stomach. Later lateral image during gastrostomy tube injection (below right) shows contrast refluxing back from the stomach along the gastrostomy tube tract into the colon which is anterior to the stomach.The diagnosis was initial malposition of the gastrostomy tube through the colon and then into the stomach.
